Whoops... forgot the speeds:

Maximum at Sea-Level: 179 Knots
75% Cruise power @ 5,500: 169 Knots.

Now, if you adopt a P337, at 16,000' with 2400 RPM and 31" MP (67% Power), your cruise speed would be 191 Knots with a total fuel burn of 144 PPH (24 GPH).

I don't have the figures for the non-pressuried but turbocharged 337H (T337H) which was only manufactured in 1978, 1979 and 1980, but one of the members of this board, Don Campbell, has one and perhaps he can provide some figures.

Keep in mind the T337H has 210 HP engines and smaller blowers, whereas the P337 (or T337G) has 225 HP engines.
